GREENSBORO, North Carolina ¨C With his third straight U.S. presidential campaign coming down to the wire, Donald Trump mused at a rally about hydrogen-powered cars exploding, lamented how difficult it is to get spray paint off limestone and marveled at how billionaire backer Elon Musk¡¯s rocket had returned to Earth in one piece.
He complained Democratic rival Kamala Harris wasn¡¯t working as hard as he was, praised Chinese President Xi Jinping as ¡°fierce¡± and called former President Barack Obama ¡°a real jerk.¡±
